Note that any changes to the resolution (-density option) must be made before specifying the file, so construct the object with no file path and then use $object->readImage('path/to/file'); otherwise the density won't change. 
Also see Imagick::setResolution.

This method uses the ImageMagick "-density {$x_resolution}x{$y_resolution}" parameter
